Heating Film

The PI Heating Film is a cutting-edge heating solution that utilizes electrical current and far infrared heating technology to deliver efficient and uniform heat. At the heart of the film lies a conductive layer—commonly composed of carbon nano-ink or a fine metal alloy—that effectively transforms electrical energy into thermal energy, radiating consistent far infrared rays across the entire surface. This smart design avoids the localized overheating issues tyPIcally found in conventional heating methods.

Material Composition and Structure

1. Core Material – Polyimide (PI):
   The polyimide heating film uses PI as its base material, renowned for exceptional thermal resistance and chemical stability. This makes the heating film highly durable and suitable for long-term, high-temperature applications.

2. Heating Layer – Nano Carbon Ink or Metal Coating:
   The heating element features high-performance conductive materials like nano carbon ink or precision metal coatings, which ensure efficient and even thermal distribution.

3. Multi-Layer Safety Design:
   The PI heating film is built with a composite structure, incorporating insulation layers on both sides of the heating component. These protective layers enhance both safety and reliability in a wide range of environments, with PI offering superb electrical insulation and thermal stability.

Key Features and Advantages

• Exceptional Heat Resistance:
  The PI material performs reliably across a broad temperature range from -200°C to 300°C, making it ideal for demanding applications.

• Energy-Efficient Performance:
  Thanks to the high energy conversion rate of the PI heating film, it delivers rapid heating with low power consumption, promoting eco-friendly operation and reduced energy costs.

• Therapeutic Far Infrared Rays:
  The film emits far infrared rays that gently penetrate subcutaneous layers to improve blood circulation, offering both warmth and wellness benefits.

• Ultra-Thin and Lightweight:
  Typically measuring just 0.1mm to 0.2mm thick, the polyimide heating film is discreet and flexible—ideal for hidden installations without compromising interior aesthetics.

• Enhanced Safety:
  With high heat resistance and excellent insulation properties, the heating film minimizes the risk of electric leakage and overheating, ensuring secure and stable operation.

Application Scenarios

Thanks to its superior material properties and innovative design, the PI heating film is widely adopted across residential, commercial, and industrial fields:

1. Underfloor Heating Systems:
   Installed beneath tile, wood, or laminate flooring, the heating film ensures even, comfortable floor temperatures.

2. Industrial Equipment Heating:
   Ideal for continuous high-temperature operations in labs, manufacturing equipment, drying chambers, and more.

3. Battery Heating Applications:
   In cold climates, the thin-film heating efficiently maintains battery temperature and performance, preventing failure.

4. Medical Equipment:
   Used in applications requiring precise temperature control, such as physical therapy pads and blood warming devices, due to the PI film’s stability and safety.
